Are you sure this was introduced by my libgcc series?  I'd like to avoid
hunting down unrelated issues.

The gas error was only introduced in a very recent gas (september 22nd), btw.

No.  I just know it is the next breakage in the sparc.

I am building with the binutils head.  So this is likely the cause.

Thanks.
